Answer: The first number that appears in both sequences is 28.

Step-by-step explanation:

Let's write down numbers from each of the sequences

Sequence 1) We need to start from 7 and multiply 4

7x4=28, 28x4=112

The sequence is 7,28,112...

Sequence 2) We need to start from 8 and add 5

5+8=13, 13+5=18, 18+5=23, 23+5=28

The sequence is 8,13,18,23,28...

They both have 28

28 is the first number that appears in both sequences.

<u>multiply by 4 starting from 7</u>

  • First sequence: 7 * <em>4</em> = <u>28</u> *<em>4</em> = 112 * <em>4</em> = 448

<u>add 5 starting from 8</u>

  • Second sequence: 8 + <em>5</em> = 13 +<em> 5</em> = 18 + <em>5</em> = 23 +<em> 5</em> = <u>28</u>

Which number is between 0.6 7/9
irakobra [83]
First we make the fractions homonym ( they must have the same denomitator)

0.6 = 6 / 10                                                  7/9

6/10 = 6 * 9 / 10 * 9 = 54 / 90                        7/9 = 7 * 10 / 9 * 10 = 70 / 90

The numbers which are between these numbers are ;

55 / 90 , 56 / 90 , 57 / 90 , 58 / 90 , 59 / 90, 60 / 90 , 61 / 90 , 62 / 90 , 63 / 90 , 64 / 90, 67 / 90 , 68 / 90 , 69 / 90

62 / 90 = 62 / 2 / 90 /2 =  31 / 45 

So the right answer is B.

Hope that helps :)
